Bert,
It is not the transformers humming, it is the caps sitting on the Al plate.
But to answer your question, no they are not humming. I again am going to
rebuild the tank the way everyone is telling me to but I tried it before and
nothing worked. When I did it the "right" way everything just sat there and
if it had a face, it would be sticking it's tounge out at me. :)-
I shall listen to the coil gods and do it again, I will post the findings.
...Everytime I get things looking a bit better.. RIP!
